HOT-WATER HEATER AND CIRCULA'I'OR.` i

Specification of Letters Patent.

Patented Nov. s, 119.10.

Application led September 2, '1909. Serial No. 517,147.

To all 'whom it may concern:

Be it known that l', JAMES KEPIIART, a. citizen of the: United States, residing at lVehster City, in the county of Hamilton and State of Iowa, have invented a new and useful ll`ot\Vater yl [eater and Circulator, of which the following a specification.

The object of this invention is to provide improved ,means for .heating and circulating water. v

My invention consists in the coi'lstrl'lction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 a perspective, partly in sec! tion, of myimproved device. Fig. 2 is a vertical section centrally of the device.

In they construction of the apparatus as "shown I. employ a boiler composed of outer. and mner walls 10, 12 and then.' connections.

The outer wall 11) preferably is shaped as a. truncated cone and is formed with a peripheral flange u. at its bottom and a smaller peripheral flange o at its top'. 'lhc inner wall 12 is formed as a cone, closed at its top and having a rim 13 at its base flared at an angle to the wall and constructed with a peripheral flange 'c vcorresponding in size with and adapted to be riveted to the flange a of the outer wall. "lhe connection as shown between the flanges a, and 0 serves to support the inner wall 12 in concentric rclation to the outer Wall 10 and also serves to close the bottom of the boiler. The space between the innerand outer walls is adapted to contain water. A cover '14 is fixed and -sealed to the flange b of the outer wall 10 and4 is rovided with an integral vertical tube d 1n which is sealed a p1' e 15, said pipe communicating through sai cover with the'interior of the outer wall 10. A plurality of straight o en-ended pipes 16 are mounted diametrica ly of the inner Awall 12 and communicate at their ends through said wall with the space between the walls.v One of the pipes 16 may be extendedV across the waterspace 'between the walls and through the lower portion of the outer wall 10 and be closed when desired by a faucet d. To avoid confusion in the drawing I show one only of the ipes 16 open at its` ends to the water space tween the walls ofthe boiler. A' as burner 17 preferably 'is'located centra ly andwithin the4 base of the boiler and discharges its products of combustion, when ignited, within the lower end portion of the inner wall 12. vA spirally shaped pipe 18 is mounted withinv and in proximity to the inner surface of the inner wall 12 and veX- tends from the bote ir `of said wall nearly to the top thereof. The spirally shaped pipe 18 communicates at one end through the inner wall 12 with the lower portion of the water space in the boiler and'communicates at its upper end throu h said inner wall with -the upper portion o the water space in the boiler. Vent tubes 19 are mounted in inclined positions in andextend through Athe upper 'portions of the walls, 10, l2 of the boiler and across the water space therein.

The vent tubes 19 are open at their ends and are adapted to discharge products of combustion from the interior of the inner Wall l2. A tee 20` is mounted on the upper en@ portion of the pipe 15 and pi es 2l .lead from aliningportsof said tee an` are adapteil to be cumufeted to rmliator's not'shown.

Pipes 22 are mounted in the lower portion of the olltcl Wall lt) ofthe b0ilel-alld :OInmunicatc. with the water space within the boiler near the bottom thereof. The pipes 22 are adapted to lead from radiators not shown. It 1s the function of the pipes 21 to lead hot water to points of use and it is the function of the pipes 22 to return cooled water to the. boiler. Thus in the use of the boiler and pipes as shown, together with the convcmtional use of radiators, not shown,

a. circulation for the water is provided' and through the use of the gas burner and pipes 16, 18, together' with the peculiar shape of the boiler, provision is made for heating such water and initiating and maintaining the circulation thereof through the medium provided.

What I claim as new and desire to secure by Letters-Patent is:

l 1. A hot water'heater comprising, in colm- 'binati`on, an outer truncated cone, an inner cone secured to'said vtruncated cone at its base only and held in concentric relation thereto, inlets at the bottom of.'said outer truncated cone andan outlet at its top, a

burner below said cone and vents at its up` per end extendingoutwardly andupwardly through said truncated cone, and a conical coil lying closely against the inner surface of said cone and communicating at its ends with the 'space between said outer and innercones. A 2. A hot water heater, comprising, in combinati'on', an outer truncated cone, an inner said cone and communicating at its ends 10 conc secured. lo said. truncated cone at its with the space between said outcr and inner base only ant-l 'held'. vin concentric relation cones, and a plurality of diamctrically disthereto, inlets En' Hic bottom of said outer posed pipes spanning the base of said inner 5 truncated cone and an outlet at its top, a cone and communicating with said spams,

burner below said cone and vents at its up- 'JAMES KEPHART. l per end extending outwardly and upwardly VVitnessesf through' said truncated cone, a conica-l coil WILL. L. CLIFToN. p
